Final answer:
The situation can be considered especially dangerous if the mountain lion is approaching you, stalking you, or if it is between you and your cubs.
Step-by-step explanation:
The situation can be considered especially dangerous if the mountain lion is approaching you, stalking you, or if it is between you and your cubs. All of these scenarios pose a significant threat and increase the danger level. Approaching you indicates the mountain lion is unafraid and may attack. Stalking you means it is actively hunting and preparing to attack. If the mountain lion is between you and your cubs, it is likely trying to protect its young and may become aggressive.
